4-(3-ethyl-4-methoxy-phenyl)-4-oxo-butyric acid is a complex organic compound with the molecular formula C13H16O5. It is a derivative of butyric acid, featuring a 3-ethyl-4-methoxy-phenyl group attached to the 4-position of the butyric acid backbone. This molecule is characterized by its ketone group (oxo) at the 4-position, which contributes to its reactivity and chemical properties. It is a white crystalline solid and is used in the synthesis of various pharmaceuticals and chemical intermediates due to its unique structure and functional groups. The compound's properties, such as its solubility and stability, are influenced by the presence of the ethyl and methoxy substituents on the phenyl ring, which can affect its interactions with other molecules and its potential applications in chemical and pharmaceutical industries.

3728-79-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3728-79-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,2 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3728-79:
(6*3)+(5*7)+(4*2)+(3*8)+(2*7)+(1*9)=108
108 % 10 = 8
So 3728-79-8 is a valid CAS Registry Number.
